ZnTe Crystal Substrate Orientation110 10x10x0.5mm 10x10x1mm For THz
Detection, THz Generation
ZnTe crystals are excellent terahertz crystals lt;110> Oriented
ZnTe crystals in which THz pulses are detected by free space
electro-optical detection.
Terahertz pulses and visible light pulses propagate in a common
line through the ZnTe crystal. The terahertz pulse produces
birefringence in the ZnTe crystal, which is read out by the
linearly polarized visible light pulse. When the visible light
pulse and the terahertz pulse are in the crystal at the same time,
the visible light polarization will be rotated by the terahertz
pulse. Using a l/4 waveplate and beam splitter polarizer and a set
of balanced photodiodes, we "map" the THz pulse amplitude by
monitoring the rotation of the visible pulse polarization of the
ZnTe crystal with respect to the THz pulse after different delay
times.
Zinc telluride crystal
ZnTe crystals are II-VI semiconductors with excellent
electro-optical properties. they have a sphalerite (ZB) structure
under natural conditions, a bandgap width of 2.3ev at room
temperature, a large second-order nonlinear coefficient and
electro-optical coefficient, and a higher efficiency in radiating
and detecting THz electromagnetic waves than other electro-optical
crystals, and thus ZnTe crystals are considered to be a better
material for THz radiation sources and detectors.ZnTe ZnTe crystals
are routinely used as terahertz radiation sources and detectors
because the <110> direction of the crystal has the best phase
match under laser pulses near 800 nm.
In addition, ZnTe crystals can be widely used in various
optoelectronic devices, such as green light-emitting diodes,
electro-optical detectors, solar cells and so on.

Q&A
Q:What are the properties of ZnTe?
A:ZnTe (zinc telluride) is a binary semiconductor with a cubic
crystal structure. It has a wide bandgap of 2.26 eV at room
temperature, making it useful for optoelectronic applications. ZnTe
exhibits high thermal stability, good electron mobility, and is
often used in infrared detectors, light-emitting diodes, and solar
cells.
